      SUBSIDIARY GUARANTEE AGREEMENT (this "Guarantee Agreement") dated as of
March __, 2004, among Seabulk International, Inc. (the "Borrower"), from each
Subsidiary Guarantor (each a "Subsidiary Guarantor" and, collectively, the
"Subsidiary Guarantors"), Fortis Capital Corp. ("Fortis") as Agent for the
Counterparties to the Swap Agreements (the "Agent for the Counterparties"),
Fortis (a "Counterparty"), NIB Capital Bank N.V. (a "Counterparty") and HBOS
Treasury Services plc (a "Counterparty" and collectively with Fortis and NIB,
the "Counterparties").

                              PRELIMINARY STATEMENT

      Pursuant to the terms of the Swap Agreements, each of the Counterparties
agreed to provide the Borrower with an interest rate swap to enable the Borrower
to manage its interest rate exposure. As a condition to providing such Swap
Agreements and any other Swap Agreements from time to time outstanding, each of
the Counterparties has requested that the Subsidiary Guarantors, jointly and
severally, guarantee the Obligations of the Borrower under the Swap Agreements
by entering into this Guarantee Agreement and securing the Subsidiary
Guarantors' obligations hereunder by granting to the Agent, on behalf of the
Counterparties, a lien in, to and under the Guarantee Collateral (as defined
herein). In order to induce the Counterparties to make the Swap Agreements to
the Borrower, the Subsidiary Guarantors have agreed to guarantee the Borrower's
Obligations under the Swap Agreements by entering into this Guarantee Agreement
and by granting to the Agent, on behalf of the Counterparties, a lien in, to and
under the Guarantee Collateral.

      NOW THEREFORE, in consideration of the mutual agreements herein contained,
the parties hereto agree as follows:

                                    ARTICLE I
                                   DEFINITIONS

            Section 1.01. Definitions. Capitalized terms used herein and not
otherwise defined herein shall have the meanings assigned to such terms in
Appendix A.

                                   ARTICLE II
                             AGREEMENT TO GUARANTEE

            Section 2.01. Obligations Guaranteed.

                  (a) The Subsidiary Guarantors, jointly and severally, hereby
      unconditionally guarantee to each of the Agent and the Counterparties (i)
      the full and prompt payment of an amount equal to each and all of the
      payments and other sums when and as the same shall become due, required to
      be paid by the Borrower under each of the Swap Agreements and (ii) the
      full and prompt performance and observance by the Borrower of the
      obligations, covenants and agreements required to be performed and
      observed by the Borrower under each of the Swap Agreements (items (i) and
      (ii), the "Subsidiary Guarantee Obligations"). The Subsidiary Guarantors
      hereby irrevocably and unconditionally agree that upon any default by the
      Borrower in the payment, when due, of any amounts (including amounts in
      respect of fees and indemnification owing to the Agent or the
      Counterparties) due under the Swap Agreements, the Subsidiary Guarantors
      will promptly pay the same within ten (10) days after receipt of written
      demand therefor from the Agent or any Counterparty. The Subsidiary
      Guarantors further hereby

<PAGE>

      irrevocably and unconditionally agree that upon any default by the
      Borrower in any of its obligations, covenants and agreements required to
      be performed and observed by the Borrower under the Swap Agreements, the
      Subsidiary Guarantors will effect the observance of such obligations,
      covenants and agreements within ten (10) days after receipt of written
      demand therefor from the Agent or any Counterparties.

                  (b) All payments by the Subsidiary Guarantors shall be paid in
      the lawful currency of the United States of America. Each and every
      default (i) in the payment of any sum required to be paid by the Borrower
      under the terms of the Swap Agreements or (ii) in the prompt performance
      and observance by the Borrower of all of the obligations, covenants and
      agreements required to be performed and observed by the Borrower under the
      terms of the Swap Agreements, shall give rise to a separate cause of
      action hereunder, and separate suits may be brought hereunder as each
      cause of action arises.

                  (c) The Subsidiary Guarantors further agree that the
      Subsidiary Guarantee Obligations constitute an absolute, unconditional,
      present and continuing guarantee of performance and payment and not of
      collection, and waive any right to require that any resort be had by the
      Agent and the Counterparties to (i) any security held by or for the
      benefit of the Agent and the Counterparties for payment of the amounts due
      under the Swap Agreements, this Guarantee Agreement or the other
      Transaction Documents, (ii) the Agent's and Counterparties' right against
      any other Person, or (iii) any other right or remedy available to the
      Agent and the Counterparties by contract, applicable law or otherwise. The
      Subsidiary Guarantee Obligations are direct, unconditional and completely
      independent of the obligations of any other Person or entity, and a
      separate cause of action or separate causes of action may be brought and
      prosecuted against the Subsidiary Guarantors without the necessity of any
      other party or previous proceeding with or exhausting any other remedy
      against any other Person who might have become liable for the indebtedness
      or of realizing upon any security held by or for the benefit of the Agent
      and the Counterparties.

                  (d) The Subsidiary Guarantors shall pay to the Agent and the
      Counterparties all reasonable costs and expenses (including, without
      limitation, reasonable attorneys' fees) incurred by the Agent and the
      Counterparties upon the occurrence of an Event of Default under any or all
      of the Transaction Agreements.

            Section 2.02. Subsidiary Guarantee Obligations of Subsidiary
Guarantors Unconditional. The Subsidiary Guarantee Obligations shall be absolute
and unconditional and shall remain in full force and effect until all sums
payable by the Borrower and the Subsidiary Guarantors under the Swap Agreements,
this Guarantee Agreement and the other Transaction Documents have been paid in
full (including, without limitation, Section 2.01 hereof), and, to the extent
permitted by law, such Subsidiary Guarantee Obligations shall not be affected,
modified, released or impaired by any state of facts or the happening from time
to time of any event, including, without limitation, any of the following,
whether or not with notice to or the consent of the Subsidiary Guarantors:

                                       2

            (a) the invalidity, irregularity, illegality, frustration or
      unenforceability of, or any defect in, (i) the Transaction Documents or
      (ii) any Guarantee Collateral security given in connection therewith;

            (w) any other occurrence whatsoever, whether similar or dissimilar
      to the foregoing.

            Section 2.03. Waiver of Notice; Expenses. The Subsidiary Guarantors
each hereby expressly waive notice from the Agent and the Counterparties of its
acceptance and reliance on the Subsidiary Guarantor's Guarantee or of any action
taken or omitted in reliance hereon. The Subsidiary Guarantors further expressly
waive diligence, presentment, demand for payment, protest, any requirement that
any right or power be exhausted or any action be taken against the Borrower or
against any other obligor under any of the Transaction Documents or against the
Guarantee Collateral or any other collateral security for the Obligations. The
Subsidiary Guarantors jointly and severally agree to pay all costs, fees,
commissions and expenses (including, without limitation, all court costs and
reasonable attorneys' fees) which may be incurred by the Agent or the
Counterparties in enforcing or attempting to enforce the Subsidiary Guarantee
Obligations following any default on the part of any or all of the Subsidiary
Guarantors hereunder, whether the same shall be enforced by suit or otherwise.

            Section 2.04. Other Security. The Agent and Counterparties may
pursue their rights and remedies against the Subsidiary Guarantors
notwithstanding (a) any other Guarantee of or security for the Subsidiary
Guarantee Obligations and (b) any action taken or omitted to be taken by the
Agent, the Counterparties or any other Person to enforce any of the rights or
remedies under such other guarantee or with respect to any other security.

            Section 2.05. No Set-off by the Subsidiary Guarantors. No set-off,
abatement, recoupment, counterclaim, reduction or diminution of an obligation,
or any defense of any kind or nature (other than performance by the Subsidiary
Guarantors of the Subsidiary Guarantee Obligations hereunder) which the
Subsidiary Guarantors have or may have with respect to a claim hereunder, shall
be available hereunder to the Subsidiary Guarantors against the Agent or the
Counterparties.

            Section 2.06. Joint and Several Obligation. Each of the Subsidiary
Guarantors hereby agrees that it is jointly and severally liable for each of the
Subsidiary Guarantee Obligations. Each of the Subsidiary Guarantors accepts
joint and several liability for all Subsidiary Guarantee Obligations hereunder
in consideration of the financial accommodation to be provided by the
Counterparties to the Borrower under the Swap Agreements, and in turn, the
Borrower to the Subsidiary Guarantors, for the mutual benefit, directly and
indirectly, of each of the Subsidiary Guarantors and in consideration of the
undertakings by each of the Subsidiary Guarantors to accept joint and several
liability for each of their Subsidiary Guarantee Obligations.

      Each of the Subsidiary Guarantors jointly and severally hereby irrevocably
and unconditionally accepts, not merely as a surety but also as a co-debtor,
joint and several liability with the other Subsidiary Guarantors with respect to
the payment and performance of all of the Subsidiary Guarantee Obligations, it
being the intention of the parties hereto that all the Subsidiary Guarantee
Obligations shall be the joint and several obligations of each of the Subsidiary
Guarantors without preferences or distinction among them.

      If and to the extent that any Subsidiary Guarantor shall fail to make any
payment with respect to any of the Subsidiary Guarantee Obligations as and when
due or to perform any of the Subsidiary Guarantee Obligations in accordance with
the terms thereof, then in each such event,

                                       5
<PAGE>

the other Subsidiary Guarantors will make such payment with respect to, or
perform, such Subsidiary Guarantee Obligations.

      The obligations of each Subsidiary Guarantor under the provisions of this
Section 2.06 constitute full recourse obligations of such Subsidiary Guarantor,
enforceable against it to the full extent of its properties and assets,
irrespective of the validity, regularity or enforceability of this Guarantee
Agreement or any other Transaction Document against another Subsidiary Guarantor
or any other circumstances whatsoever that under applicable law might constitute
a defense to the joint and several Subsidiary Guarantee Obligations of such
other Subsidiary Guarantor.

      Except as otherwise expressly provided herein, each Subsidiary Guarantor
hereby waives notice of acceptance of its joint and several liability, notice of
any and all Subsidiary Guarantee Obligations incurred hereunder or under any
other Transaction Document, notice of the occurrence of any Default or Event of
Default, or of any demand for any payment hereunder or any other Transaction
Document, notice of any action at any time taken or omitted by the Agent or any
Counterparty under or in respect of any of the Subsidiary Guarantee Obligations,
any requirement of diligence and, generally, all demands, notices and other
formalities of every kind in connection with the Subsidiary Guarantee
Obligations, this Guarantee Agreement or any other Transaction Document. Each
Subsidiary Guarantor hereby assents to, and waives notice of, any extension or
postponement of the time for the payment of any of the Subsidiary Guarantee
Obligations, the acceptance of any partial payment thereon, any waiver, consent
or other action or acquiescence by the Agent or any Counterparty at any time or
times in respect of any default by any Subsidiary Guarantor in the performance
or satisfaction of any term, covenant, condition or provision hereunder or under
this Guarantee Agreement or any other Transaction Document, any and all other
indulgences whatsoever by the Agent or any Counterparty in respect of any of the
Subsidiary Guarantee Obligations, and the taking, addition, substitution or
release, in whole or in part, at any time or times, of any security for any of
the Subsidiary Guarantee Obligations or the addition, substitution or release,
in whole or in part, of any Subsidiary Guarantor. Without limiting the
generality of the foregoing, each Subsidiary Guarantor assents to any other
action or delay in acting or failure to act on the part of the Agent or any
Counterparty, including, without limitation, any failure strictly or diligently
to assert any right or to pursue any remedy or to comply fully with applicable
laws or regulations thereunder which might, but for the provisions of this
Section 2.06, afford grounds for terminating, discharging or relieving such
Subsidiary Guarantor, in whole or in part, from any of its obligations under
this Section 2.06, it being the intention of each Subsidiary Guarantor that, so
long as any of the Subsidiary Guarantee Obligations remain unsatisfied, the
obligations of such Subsidiary Guarantor shall not be discharged except by
performance and then only to the extent of such performance. The Subsidiary
Guarantee Obligations of each Subsidiary Guarantor shall not be diminished or
rendered unenforceable by any winding up, reorganization, arrangement,
liquidation, reconstruction or similar proceeding with respect to the Borrower
or the other Subsidiary Guarantors or any Counterparty. The joint and several
liability of the Subsidiary Guarantors hereunder shall continue in full force
and effect notwithstanding any absorption, merger, amalgamation or any other
change whatsoever in the name, membership, constitution or place of formation of
the Borrower, any Subsidiary Guarantor or any Counterparty.

                                       6
<PAGE>

      The provisions of this Section 2.06 are made for the benefit of the Agent
and each Counterparty and their successors and assigns, and may be enforced by
such party from time to time against any of the Subsidiary Guarantors as often
as occasion therefore may arise and without requirement on the part of the Agent
or any Counterparty first to marshal any of its claims or to exercise any of its
rights against any Subsidiary Guarantor or to exhaust any remedies available to
it against any Subsidiary Guarantor or to resort to any other source or means of
obtaining payment of any of the Subsidiary Guarantee Obligations or to elect any
other remedy. The provisions of this Section 2.06 shall remain in effect until
all the Subsidiary Guarantee Obligations shall have been paid in full or
otherwise fully satisfied. If at any time, any payment, or any part thereof,
made in respect of any of the Subsidiary Guarantee Obligations, is rescinded or
must otherwise be restored or returned by the Agent or any Counterparty upon the
insolvency, bankruptcy or reorganization of either of the Subsidiary Guarantors,
or otherwise, the provisions of this Section 2.06 will forthwith be reinstated
in effect, as though such payment had not been made.

            Section 2.07. Limitation on Liability. Any term or provision of this
Guarantee Agreement or any other Transaction Document to the contrary
notwithstanding, the maximum, aggregate amount of the Obligations guaranteed
hereunder by any Subsidiary Guarantor shall not exceed the maximum amount that
can be hereby guaranteed without rendering this Guarantee Agreement or any other
Transaction Document, as it relates to such Subsidiary Guarantor, voidable under
applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

            Section 2.08. Release of Subsidiary Guarantor. So long as no Default
or Event of Default has occurred and is continuing, upon the sale or other
disposition (including by way of consolidation or merger) of a Subsidiary
Guarantor or the sale or disposition of all or substantially all the assets of
such Subsidiary Guarantor in compliance with the terms of this Guarantee
Agreement, such Subsidiary Guarantor shall be deemed released from all
obligations under this Article II without any further action required on the
part of the Agent or any Counterparty. At the request and sole cost and expense
of such Subsidiary Guarantor, the Agent shall execute and deliver an appropriate
instrument evidencing such release.

                                   ARTICLE III
           REPRESENTATIONS AND WARRANTIES OF THE SUBSIDIARY GUARANTORS

      In order to induce the Agent and the Counterparties to enter into this
Guarantee Agreement and to induce the Counterparties to make the Swap Agreements

warranties shall survive the execution and delivery of this Guarantee Agreement
and the Transaction Documents) that:

taken all necessary action to authorize the execution, delivery and performance
by it of each of such Transaction Documents. Each Subsidiary Guarantor has duly
executed and delivered each of the Transaction Documents to which it is party,
and each of such Transaction Documents constitutes the legal, valid and binding
obligation of such Subsidiary Guarantor enforceable in accordance with its
terms, except to the extent that such enforceability may be limited by any
applicable bankruptcy, insolvency or similar laws generally affecting the
enforcement of creditor's rights and by general principles of equity.

            Section 3.03. No Violation. Neither the execution, delivery or
performance by any Subsidiary Guarantor of the Transaction Documents to which it
is a party, nor compliance by it with the terms and provisions thereof, (i) will
contravene any provision of any applicable law, statute, rule or regulation or
any applicable order, writ, injunction or decree of any court or governmental
instrumentality, other than any such contravention that could not reasonably be
expected to result in a Material Adverse Change, (ii) will conflict with or
result in any breach of any of the terms, covenants, conditions or provisions
of, or constitute a default under, or result in the creation or imposition of
(or the obligation to create or impose) any Lien (except pursuant to the
Security Documents) upon any of the material properties or assets of the
Subsidiary Guarantors pursuant to the terms of, any indenture, mortgage, deed of
trust, credit agreement or loan agreement, or any other material agreement,
contract or instrument, to which any Subsidiary Guarantor is a party or by which
it or any of its property or assets is bound or to which it may be subject, or
(iii) will violate any provision of the Certificate of Incorporation or other
documents of any Subsidiary Guarantor.

            Section 3.04. Governmental Approvals. Except (a) as otherwise
disclosed in writing to the Counterparties on or prior to the date hereof, (b)
for filings and recordings in connection with the Security Documents (which

Collateral delivered as of the Date hereof) and (c) as have been obtained and
are in effect, no order, consent, approval, license, authorization or validation
of, or filing, recording or registration with or exemption by, any governmental
or public body or authority, or any subdivision thereof, is required to
authorize, or is required in connection with, (i) the consummation and
performance by any Subsidiary Guarantor of any Transaction Document to which it
is a party or (ii) the legality, validity, binding effect or enforceability of
any Transaction Document to which it is a party.

            Section 3.05. Litigation. Except as disclosed in Schedule 3.05
hereto, there is no action, suit, proceeding or investigation pending or, to the
best knowledge of each Subsidiary Guarantor, threatened, before any court or
administrative agency that might: (i) adversely affect its ability to perform
its obligations under this Guarantee Agreement or any other Transaction Document
to which it is a party, (ii) reasonably be expected to result in any judgment or
liability which would result in a Material Adverse Change or (iii) adversely
affect the enforceability of this Guarantee Agreement or any Transaction
Document.

any financial commitment or obligation.

has filed or caused to be filed, with the appropriate taxing authority, all
federal, state, provincial and other returns, statements, forms and reports for
Taxes (the "Returns") required to be filed by or with respect to the income,
properties or operations of the Subsidiary Guarantors except where the failure
to so file or cause to be filed could not reasonably be expected to result in a
Material Adverse Change. The Subsidiary Guarantors have paid all Taxes payable
by them other than (a) Taxes which are not delinquent, (b) Taxes contested in
good faith for which adequate reserves have been established in accordance with
GAAP and (c) foreign Taxes as to which the failure to pay such foreign Taxes

      that could adversely affect the qualification of such Plan; (iii) the most

language other than English and other matters, in each case in respect of which

      Subsidiary Guarantor under this Guarantee Agreement and the other
      Transaction Documents pursuant to a written supplement to this Guarantee
      Agreement executed in accordance with Article VIII.

            (b) Immediately prior to and after giving effect to such
      transaction, no Default or Event of Default shall have occurred and be
      continuing and the Agent shall have received a certificate from an
      Executive Officer to such effect.

            (c) The Agent shall have received an opinion of counsel regarding
      the merged or consolidated entity, the legality, validity and
      enforceability of this Guarantee Agreement and the other Transaction
      Documents, the title to the related Vessels and the priority of the
      Mortgages, as applicable.

                                       19

            (d) Upon any consolidation or merger, or any conveyance or transfer
      of substantially all of the assets of such Subsidiary Guarantor as an
      entirety in accordance with this Section 5.12, the successor entity formed
      by such consolidation or into which such Subsidiary Guarantor is merged or
      to which such conveyance or transfer is made shall succeed to, and be
      substituted for, and may exercise every right and power of, such
      Subsidiary Guarantor under this Guarantee Agreement and the other
      Transaction Documents with the same effect as if such successor entity had
      been named as a Subsidiary Guarantor herein. No such conveyance or
      transfer of substantially all of the assets of such Subsidiary Guarantor
      as an entirety shall have the effect of releasing such Subsidiary
      Guarantor or any successor entity which shall theretofore have become such
      in the manner prescribed in this Section 5.12 from its liability
      hereunder. Nothing in this Section 5.12 shall restrict the Subsidiary
      Guarantors from chartering the Vessels so long as such charters are not
      bareboat charters for a period in excess of ten (10) years, except with
      respect to bareboat charters of the Third Lien Vessels so long as MARAD is
      the first mortgagee thereon, which shall not be subject to any such
      restriction.

      Obligations, cease to be, or be asserted by a Subsidiary Guarantor not to
      be, a legal, valid and binding obligation of such Subsidiary Guarantor,
      enforceable in accordance with its terms, except to the extent that such

                                       21
<PAGE>

      enforceability may be limited by any applicable bankruptcy, insolvency or

      by general principles of equity;

            (l) if a Subsidiary Guarantor shall default (as principal or
      guarantor or other surety) in any payment on any obligation for money
      borrowed, beyond any period of grace provided with respect thereto, or if
      any other default under any agreement under which any such obligation is
      created or under any instrument securing or evidencing such obligation,

      permit the holder of such obligation to cause, such obligation to become
      due prior to its stated maturity;

            (m) if a Subsidiary Guarantor ceases to be a direct or indirect

      Guarantor that represents a reasonably foreseeable likelihood of the
      nonpayment of the Subsidiary Guarantee Obligations.

            Section 6.02. Waiver of Default. Any Event of Default may be waived
only with the written consent of the Requisite Counterparties. Any Event of
Default so waived shall be deemed to have been cured and not to be continuing;
but no such waiver shall be deemed a continuing waiver or shall extend to or
affect any subsequent like default or impair any rights arising therefrom.

            Section 6.03. Remedies. Upon the occurrence and continuance of any
Event of Default, the Requisite Counterparties or the Agent, on behalf and for
the ratable benefit of the Counterparties, may, at the option of Requisite
Counterparties, without first proceeding against or exhausting any other
remedies which such party may have and without resorting to any other security
held by the Subsidiary Guarantors under the Transaction Documents, do any one or
more of the following, all of which are hereby authorized by the Subsidiary
Guarantors:

            (a) Declare all or any of the Subsidiary Guarantee Obligations of
      the Subsidiary Guarantors under this Guarantee Agreement and any other
      instrument executed by the Subsidiary Guarantors pursuant to the
      Transaction Documents to be immediately due and payable, and upon such
      declaration such obligations so declared due and payable shall immediately
      become due and payable; provided, however, that if such Event of Default
      is under either Sections 6.01(e), (f), (g) or (h), then all of the
      Subsidiary Guarantee Obligations shall become immediately due and payable
      forthwith without the requirement of any notice or other action by the
      Counterparties or the Agent;

            (b) Exercise any or all of the rights and powers and pursue any and
      all of the remedies pursuant to this Article and any of the other
      Transaction Documents, to the extent permitted by applicable law; and

                                       22
<PAGE>

            (c) Bring suit at law or in equity, to recover judgment for the
      Subsidiary Guarantee Obligations hereby secured, and collect the same out
      of any and all of any or all of the Subsidiary Guarantors' property and
      the Guarantee Collateral.

            Section 6.04. Rights of Set-Off. Regardless of the adequacy of any
Guarantee Collateral, during the continuance of an Event of Default, any
deposits or other sums credited by or due from any Counterparty to the Borrower
may be set-off against the Subsidiary Guarantor Obligations and any and all
other liabilities, direct or indirect, absolute or contingent, due or to become
due, now existing or hereafter arising, of the Subsidiary Guarantors to the
Counterparties. Any Counterparty that exercises any such set-off right shall use
reasonable diligence to notify the Subsidiary Guarantors of any such exercise,
provided that the failure of such Counterparty to provide any such notice shall
not affect the validity of such Counterparty's exercise of such set-off right.

            Section 6.05. Rights and Remedies Cumulative. The Counterparties'
and the Agent's rights and remedies under this Guarantee Agreement shall be
cumulative and shall be in addition to every other right, power and remedy
herein specifically given or now or hereafter existing at law, in admiralty, in
equity or by statute, and each and every right, power and remedy whether
specifically herein given or otherwise existing may be exercised from time to
time and as often and in such order as may be deemed expedient by the Agent or
the Counterparties, and the exercise or the beginning of the exercise of any
power or remedy shall not be construed to be a waiver of the right to exercise
at the same time or thereafter any other right, power or remedy. The
Counterparties and the Agent shall have all other rights and remedies not
inconsistent herewith as provided by law or in equity. No exercise by any
Counterparty or the Agent of one right or remedy shall be deemed an election. No
delay or omission by any Counterparty or the Agent shall constitute a waiver,
election or acquiescence by such party.

            Section 6.06. Specific Remedies. Upon the occurrence and during the
continuance of an Event of Default:

            (a) At the request of the Agent, each Subsidiary Guarantor shall
      promptly execute and deliver such instruments and other documents as the
      Agent may deem necessary or advisable to enable the Agent to obtain
      possession of all or any part of the Guarantee Collateral to which
      possession the Counterparties shall at the time be entitled hereunder. If
      a Subsidiary Guarantor shall for any reason fail to execute and deliver
      such instruments and documents after such request by the Agent, the Agent
      may obtain a judgment conferring on the Agent the right to such possession
      on behalf of the Counterparties immediately and requiring such Subsidiary
      Guarantor to deliver such instruments and documents to the Agent, to the
      entry of which judgment such Subsidiary Guarantor hereby specifically
      consents.

            (b) The Agent, on behalf of the Counterparties, may proceed to
      enforce the rights of the Counterparties by directing payment to it of all
      monies payable under any agreement or undertaking constituting a part of
      the Guarantee Collateral, by proceedings in any court of competent
      jurisdiction for the appointment of a receiver or for the sale of all or
      any part of the Guarantee Collateral, possession to which the
      Counterparties shall at the time be entitled hereunder, or for foreclosure
      of such Guarantee Collateral, and by

                                       23
<PAGE>

      any other action, suit, remedy or proceeding authorized or permitted by
      this Guarantee Agreement or by law or by equity, and may file such proofs
      of claim and other papers or documents as may be necessary or advisable in
      order to have the claims of the Counterparties asserted or upheld in any
      bankruptcy, receivership or other judicial proceedings.

            (c) The Agent shall be entitled to set-off against and withdraw all
      amounts constituting a part of the Collateral and to apply the same as
      follows:

            First: To the payment of all reasonable expenses and charges,
            including the expenses of any taking, operating, attorney's fees,
            court costs and other expenses or advances made or incurred by the
            Agent in connection with the ascertainment or protection of its
            rights and the pursuance of its remedies hereunder or under any of
            the other Transaction Documents (including, without limitation, the
            reasonable fees and disbursements of counsel);

            Second: To the payment of the Swap Obligations;

            Third: To the payment of all amounts due to the Agent and the
            Counterparties in respect of taxes, indemnities, fees, expenses,
            premiums, purchase of liens or otherwise under the provisions hereof
            or under any of the other Transaction Documents;

            Fourth: To the payment of the Guarantee Obligations, other than
            those referred to in First through Third above; and

            Fifth: To the payment of any surplus thereafter remaining to the
            Borrower or whomever may be lawfully entitled thereto.

            (d) Without limiting the foregoing, the Agent and the
      Counterparties, their respective assigns and legal representatives shall
      have all the remedies of a secured party under applicable law and such
      further remedies as from time to time may hereafter be provided pursuant
      to such law for a secured party.

            Section 6.07. Restoration of Rights and Remedies. In case the Agent
or a Counterparty shall have proceeded to enforce any right, power or remedy
under this Guarantee Agreement by foreclosure, entry or otherwise, and such
proceedings shall have been discontinued or abandoned for any reason or shall
have been determined adversely to the Agent or such Counterparty, then and in
every such case the Subsidiary Guarantors, the Agent and the Counterparties
shall be restored to their former positions and rights hereunder with respect to
the Guarantee Collateral, and all rights, remedies and powers of the Agent and
the Counterparties shall continue as if no such proceedings had been taken.

            Section 6.08. Cure of Defaults. Subject to the terms of this
Guarantee Agreement, if at any time after an Event of Default, the Subsidiary
Guarantors offer completely to cure all Events of Default and to pay all
expenses, advances and damages to the Agent and the Counterparties consequent on
such Events of Default, with interest with respect to such Subsidiary
Guarantor's obligations as provided herein, then the Agent may, but shall not be

                                       24
<PAGE>

required to, accept such offer and payment and restore the Subsidiary Guarantors
to its former position, but such action, if taken, shall not affect any
subsequent Event of Default or impair any rights consequent thereon.

                                   ARTICLE VII
                      RELATIONSHIP AMONG THE COUNTERPARTIES

            Section 7.01. Appointment and Authorization. Each Counterparty
hereby irrevocably appoints, designates and authorizes Fortis as the Agent under
this Guarantee Agreement and under each of the other Transaction Documents and
irrevocably authorizes the Agent to take such action on its behalf under the
provisions of this Guarantee Agreement and each other Transaction Document and
to exercise such powers and perform such duties as are expressly delegated to it
by the terms of this Guarantee Agreement or any other Transaction Document,
together with such powers as are reasonably incidental thereto. Notwithstanding
any provision to the contrary contained elsewhere in this Guarantee Agreement or
in any other Transaction Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Counterparty, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Guarantee Agreement or any other Transaction
Document or otherwise exist against the Agent.

            Section 7.02. Delegation of Duties. The Agent may execute any of its
duties under this Guarantee Agreement or any other Transaction Document by or
through agents, employees or attorneys-in-fact and shall be entitled to advice
of counsel concerning all matters pertaining to such duties. The Agent shall not
be responsible for the gross negligence or misconduct of any agent or
attorney-in-fact that it selects with reasonable care or for any action it takes
on the advice of counsel.

            Section 7.03. Liability of Agent. None of the Agent-Related Persons
shall (a) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Guarantee Agreement or any other Transaction
Document (except for its own gross negligence or willful misconduct), (b) be
liable as a consequence of any failure or delay in performance by, or any breach
by, any other Counterparty or any other Person, of its obligations under this
Guarantee Agreement or any other Transaction Document or (c) be responsible in
any manner to any Counterparty for any recital, statement, representation or
warranty made by a Transaction Party, or any officer thereof, contained in this
Guarantee Agreement or in any other Transaction Document, or in any certificate,
report, statement or other document referred to or provided for in, or received
by the Agent under or in connection with, this Guarantee Agreement or any other
Transaction Document, or for the value of any Guarantee Collateral or the
validity, effectiveness, genuineness, enforceability or sufficiency of this
Guarantee Agreement or any other Transaction Document, or for any failure of a
Transaction Party or any other party to this Guarantee Agreement or any other
Transaction Document to perform its obligations hereunder or thereunder. No
Agent-Related Person shall be under any obligation to any Counterparty to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Guarantee Agreement or any other
Transaction Document, or to inspect the properties, books or records of any
Transaction Party.

            Section 7.04. Reliance by the Agent. (a) The Agent shall be entitled
to rely, and shall be fully protected in relying, upon (i) any writing,
resolution, notice, consent,

                                       25
<PAGE>

certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and (ii) any advice or statements of legal counsel (including counsel to the
Subsidiary Guarantors), independent accountants and other experts selected by
the Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Guarantee Agreement or any other Transaction Document unless
it shall first receive such advice or concurrence of the Requisite
Counterparties as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by the Counterparties against any and all
liability and expense which may be incurred by it by reason of taking or
continuing to take any such action. The Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Guarantee
Agreement or any other Transaction Document in accordance with a request or
consent of the Requisite Counterparties and such request and any action taken or
failure to act pursuant thereto shall be binding upon all of the Counterparties.

            (b) For purposes of determining compliance with the conditions
      precedent specified in Section 8.22, each Counterparty that has executed
      this Guarantee Agreement shall be deemed to have consented to, approved or
      accepted or to be satisfied with each document or other matter either sent
      by the Agent to such Counterparty for consent, approval, acceptance or
      satisfaction, or required thereunder to be consented to or approved by or
      acceptable or satisfactory to the Counterparty.

            Section 7.05. Notice of Default. The Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
unless the Agent shall have received written notice from a Counterparty or a
Subsidiary Guarantor referring to this Guarantee Agreement, describing such
Default or Event of Default and stating that such notice is a "notice of
default". In the event that the Agent receives such a notice, the Agent shall
give notice thereof to the Counterparties. The Agent shall take such action with
respect to such Default or Event of Default as shall be requested by the
Requisite Counterparties in accordance with this Guarantee Agreement; provided,
however, that unless and until the Agent shall have received any such request,
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable or in the best commercial interest of the Counterparties.

            Section 7.06. Credit Decision. Each Counterparty expressly
acknowledges that none of the Agent-Related Persons has made any representation
or warranty to it and that no act by the Agent hereinafter taken, including any
review of the affairs of a Transaction Party, shall be deemed to constitute any
representation or warranty by the Agent to any Counterparty. Each Counterparty
represents to the Agent that it has, independently and without reliance upon the
Agent and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Transaction Parties, and all applicable Counterparty regulatory laws relating to
the transactions contemplated thereby, and made its own decision to enter into
this Guarantee Agreement and extend credit to the Borrower under and pursuant to
this Swap Agreements. Each Counterparty also represents that it will,
independently and without reliance upon the Agent and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Guarantee Agreement and the other Transaction Documents, and to make
such investigations as it deems necessary to inform itself as to the

                                       26
<PAGE>

business, prospects, operations, property, financial and other condition and
creditworthiness of the Subsidiary Guarantors. Except for notices, reports and
other documents expressly herein required to be furnished to the Counterparties
by the Agent, the Agent shall not have any duty or responsibility to provide any
Counterparty with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Subsidiary Guarantors, which may come into the
possession of any of the Agent-Related Persons.

            Section 7.07. Indemnification. Whether or not the transactions
contemplated hereby shall be consummated, the Counterparties shall indemnify
upon demand the Agent-Related Persons (to the extent not reimbursed by or on
behalf of the Subsidiary Guarantors and without limiting the obligation of the
Subsidiary Guarantors to do so), ratably from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements of any kind whatsoever which may at any time
(including at any time following the repayment of the Swap Agreements and the
termination or resignation of the related Agent) be imposed on, incurred by or
asserted against any such Person in any way relating to or arising out of this
Guarantee Agreement, the Transaction Documents or any document contemplated by
or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by any such Person under or in connection
with any of the foregoing; provided, however, that no Counterparty shall be
liable for the payment to the Agent-Related Persons of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from such Agent-Related Person's
gross negligence or willful misconduct. Without limiting the foregoing, each
Counterparty shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including reasonable attorney fees) incurred by
the Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings or otherwise) of, or legal advice in respect of
rights or responsibilities under this Guarantee Agreement, any other Transaction
Document, or any document contemplated by or referred to herein to the extent
that the Agent is not reimbursed for such expenses by or on behalf of the
Subsidiary Guarantors. The obligation of the Counterparties in this Section 7.07
shall survive the payment of the Subsidiary Guarantee Obligations.

            Section 7.08. Agent in Individual Capacity. Fortis and its
affiliates may make loans to, issue letters of credit for the account of, accept
deposits from, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory or other business with the Subsidiary
Guarantors and any of its affiliates as though Fortis were not the Agent
hereunder and without notice to or consent of the Counterparties. Fortis shall
have the same rights and powers under this Guarantee Agreement as any other
Counterparty and may exercise the same as though it were not the Agent, and the
terms "Counterparty" and "Counterparties" shall include Fortis in its individual
capacity.

            Section 7.09. Successor Agent. The Agent may resign as Agent upon
thirty (30) days' notice to the Counterparties. If the Agent shall resign as
Agent under this Guarantee Agreement, the Requisite Counterparties shall appoint
from among the Counterparties a successor agent for the Counterparties. If no
successor agent is appointed prior to the effective date of the resignation of
the Agent, the Agent may appoint, after consulting with the Counterparties and
the Subsidiary Guarantors, a successor agent from among the Counterparties.

                                       27

Upon the acceptance of its appointment as successor agent hereunder, such
successor agent shall succeed to all the rights, powers and duties of the
retiring Agent and the term "Agent" shall mean such successor agent and the
retiring Agent's appointment, powers and duties as Agent shall be terminated.
After any retiring Agent's resignation hereunder as Agent, the provisions of
this Article X shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Guarantee Agreement. If no
successor agent has accepted appointment as Agent by the date which is thirty
(30) days following a retiring Agent's notice of resignation, the retiring
Agent's resignation shall nevertheless thereupon become effective and the
Counterparties shall perform all of the duties of the Agent hereunder until such
time, if any, as the Requisite Counterparties appoint a successor agent as
provided for above. Any successor Agent appointed under this Section 7.09 shall
be reasonably acceptable to the Subsidiary Guarantors.

            Section 7.10. Collateral Matters. (a) The Agent is authorized on
behalf of all the Counterparties, without the necessity of any notice to or
further consent from the Counterparties, from time to time to take any action
with respect to the Guarantee Collateral which may be necessary to perfect and
maintain perfected the security interest in and Liens upon the Guarantee
Collateral granted pursuant thereto.

            (b) The Counterparties irrevocably authorize the Agent, at its
      option and in its discretion, to release any Lien granted to or held by
      the Agent upon any Guarantee Collateral (i) upon payment in full of all of
      Subsidiary Guarantee Obligations then payable under this Guarantee
      Agreement and under any other Transaction Document; (ii) consisting of an
      instrument evidencing Indebtedness or other debt instrument, if the
      indebtedness evidenced thereby has been paid in full; (iii) if approved,
      authorized or ratified in writing by all of the Counterparties or (iv)
      upon any sale, transfer, assignment or other disposition of any Guarantee
      Collateral, to the extent that the same is expressly permitted by the
      terms of this Guarantee Agreement and the other Transaction Documents.
      Upon request by the Agent at any time, the Counterparties will confirm in
      writing the Agent's authority to release particular types or items of
      Collateral pursuant to this Section 7.10(b).

                                  ARTICLE VIII
                                  MISCELLANEOUS

            Section 8.01. Notices. (a) All notices, requests, approvals and
other communications provided for hereunder shall be in writing (including,
unless the context expressly otherwise provides, by facsimile transmission,
provided that any matter transmitted by a Subsidiary Guarantor by facsimile (i)
shall be immediately confirmed by a telephone call to the recipient at the
number specified on the applicable signature page hereof, and (ii) shall be
followed promptly by a hard copy original thereof) and mailed, faxed or
delivered, to the address or facsimile number specified for notices on the
applicable signature page hereof or, as directed to a Subsidiary Guarantor or
the Agent, to such other address as shall be designated by such party in a
written notice to the other parties, and as directed to each other party, at
such other address as shall be designated by such party in a written notice to a
Subsidiary Guarantor and the Agent.

            (b) All such notices, requests and communications shall, when
      transmitted by overnight delivery, or faxed, be effective when delivered
      for overnight (next day)

                                       28
<PAGE>

      delivery, or transmitted by facsimile machine, respectively, or if
      delivered, upon delivery, except that notices pursuant to Article VIII
      shall not be effective until actually received by the Agent.

            (c) Each Subsidiary Guarantor acknowledges and agrees that any
      agreement of the Agent and the Counterparties to receive certain notices
      by telephone and facsimile is solely for the convenience and at the
      request of such Subsidiary Guarantor. The Agent and the Counterparties
      shall be entitled to rely on the authority of any Person purporting to be
      a Person authorized by such Subsidiary Guarantor to give such notice and
      the Agent and the Counterparties shall not have any liability to the
      Subsidiary Guarantors or other Person on account of any action taken or
      not taken by the Agent or the Counterparties in reliance upon such
      telephonic or facsimile notice. The obligation of Subsidiary Guarantors to
      pay the Subsidiary Guarantee Obligations shall not be affected in any way
      or to any extent by any failure by the Agent and the Counterparties to
      receive written confirmation of any telephonic or facsimile notice or the
      receipt by the Agent and the Counterparties of a confirmation which is at
      variance with the terms understood by the Agent and the Counterparties to
      be contained in the telephonic or facsimile notice.

            Section 8.02. Survival of Agreement. All covenants, agreements,
representations and warranties made herein and in the certificates delivered
pursuant hereto shall survive the making and delivery of this Guarantee
Agreement to the Agent and the Counterparties, and shall continue in full force
and effect so long as the Subsidiary Guarantee Obligations remain outstanding.

            Section 8.03. Governing Law. This Guarantee Agreement shall be
governed by and interpreted in accordance with the laws of the State of New
York, without giving effect to the principles of conflicts of law.

            Section 8.04. Modification of Agreement. No amendment, modification
or waiver of any provision of this Guarantee Agreement or any other Transaction
Document, and no consent with respect to any departure by a Subsidiary Guarantor
therefrom, shall be effective unless the same shall be in writing and signed by
the Requisite Counterparties and acknowledged by the Agent, and then such waiver
shall be effective only in the specific instance and for the specific purpose
for which given; provided, however, that no such waiver, amendment, or consent
shall, unless in writing and signed by each Counterparty affected thereby and
acknowledged by the Agent, do any of the following:

            (a) postpone or delay any date fixed for the payment of any
      Subsidiary Guarantee Obligations;

            (b) amend this Section 7.04; or

            (c) release all or any part of the Guarantee Collateral or release
      any Subsidiary Guarantor from its liabilities as a joint and several

      Obligations as described in Section 2.06, hereof;

                                       29
<PAGE>

and, provided further that no amendment, modification, waiver or consent shall,
unless in writing and signed by the Agent in addition to the Requisite
Counterparties or all the Counterparties, as the case may be, affect the rights
or duties of the Agent under this Guarantee Agreement or any other Transaction
Document.

            Section 8.05. Costs and Expenses. Each Subsidiary Guarantor agrees
whether or not the transactions contemplated hereby shall be consummated, to:

            (a) pay or reimburse the Agent within five (5) Business Days after
      demand for all costs and expenses incurred by the Agent in connection with
      the development, preparation, delivery, administration and execution of,
      and any amendment, supplement, waiver or modification to (in each case,
      whether or not consummated), this Guarantee Agreement, any other
      Transaction Document and any other documents prepared in connection
      herewith (including any commitment letter and related documents preceding
      this Guarantee Agreement) or therewith, and the consummation of the
      transactions contemplated hereby and thereby, including the attorney costs
      incurred by the Agent with respect hereto and thereto;

            (b) pay or reimburse the Agent and each Counterparty within five (5)
      Business Days after demand for all costs and expenses incurred by them in
      connection with the enforcement, attempted enforcement, or preservation of
      any rights or remedies (including in connection with any insolvency
      proceedings or appellate proceeding) under this Guarantee Agreement, any
      other Transaction Document, and any such other documents, including
      attorney costs incurred by the Agent and any Counterparty; and

            (c) pay or reimburse the Agent within five (5) Business Days after
      demand for all reasonable audit, environmental inspection and review,
      search and filing, registration and recording costs, fees and expenses,
      incurred or sustained in connection with the matters referred to under
      Section 7.05(a) and Section 7.05(b).

            Section 8.06. Waivers Section 1.01 . No waiver of any of the
provisions of this Guarantee Agreement (a) shall be valid unless evidenced by a
writing executed by each party to be bound thereby, (b) shall be deemed or shall
constitute a waiver of any other provision of this Guarantee Agreement or any
other provisions hereof (whether or not similar), or (c) shall constitute a
continuing waiver unless otherwise expressly provided. No delay on the part of
the Agent or any Counterparty in exercising any right or remedy hereunder shall
operate as a waiver thereof nor shall any single or partial exercise of any
power or right or remedy preclude other or further exercise thereof or the
exercise of any other right or remedy. No notice to or demand on a Subsidiary
Guarantor in any case shall entitle it to any other or further notice or demand
in the same or similar circumstances.

            Section 8.07. Indemnification. To the fullest extent permitted by
law, the Subsidiary Guarantors agree, jointly and severally, to protect,
indemnify, defend and hold harmless the Agent, each Counterparty and each of
their respective directors, officers, employees and agents and any Person who
controls any of them within the meaning of the federal, provincial, state and
foreign securities laws (each an "Indemnitee") from and against any liabilities,
losses, obligations, damages, penalties, expenses or costs of any kind or nature
and from any suits, judgments, claims or demands (including in respect of or for
attorney costs and other reasonable fees and other disbursements of counsel for
and consultants of any Indemnitees

                                       30
<PAGE>

in connection with any investigative, administrative or judicial proceeding,
whether or not such Indemnitees shall be designated a party thereto) based on
any federal, provincial, state, local or foreign law or other statutory
regulation, including securities, environmental and commercial law or other
statutory regulation, which arises under common law or at equitable cause or on
contract or otherwise on account of or in connection with any matter or thing or
any action or failure to act by the Indemnitees, or any of them, arising out of
or relating to the Transaction Documents or any agreement or instrument
contemplated by the Transaction Documents, but excluding those arising (x) by
reason of gross negligence or willful misconduct of the Agent or any Indemnitee,
or (y) in respect of Taxes (as to which indemnification shall be applicable only
as and to the extent set forth in the Swap Agreements). Upon receiving knowledge
of any suit, claim or demand asserted by any Person that an Indemnitee believes
is covered by this indemnity, such Indemnitee shall give the Subsidiary
Guarantors notice thereof and an opportunity to defend it, at the Subsidiary
Guarantors' sole cost and expense, with legal counsel reasonably satisfactory to
such Indemnitee. Such Indemnitee may also require the Subsidiary Guarantors to
defend the matter. The obligations of the Subsidiary Guarantors under this
Section 8.07 shall survive the payment and performance of the Subsidiary
Guarantee Obligations and the termination of this Guaranty. To the extent that
the undertaking to indemnify, pay and hold harmless set forth in this Section
8.07 may be unenforceable because it violates any law or public policy, each of
the Subsidiary Guarantors shall contribute the maximum portion which it is
permitted to pay and satisfy under applicable law to the payment and
satisfaction of its obligations set forth in this Section 8.07.

            Section 8.08. Separability of Provisions. (a) If any provision of
this Guarantee Agreement or any Mortgage or other Transaction Document should be
deemed invalid or shall be deemed to affect adversely the preferred status of
any Mortgage under any applicable law, such provision shall be void and of no
effect and shall cease to be a part of this Guarantee Agreement and such
Mortgage or other Transaction Document without affecting the remaining
provisions, which shall remain in full force and effect.

            (a) In the event that this Guarantee Agreement, any Transaction
      Document, any Mortgage or any of the documents or instruments which may
      from time to time be delivered hereunder or thereunder or any provision
      hereof or thereof shall be deemed invalidated by present or future law of
      any nation or by decision of any court, or if any third party shall fail
      or refuse to recognize any of the powers granted to the Agent hereunder
      when it is sought to exercise them, this shall not affect the validity
      and/or enforceability of all or any other parts of this Guarantee
      Agreement, any Transaction Document, any Mortgage or such documents or
      instruments and, in any such case, the Subsidiary Guarantors covenant and
      agree that, on demand, they will execute and deliver such other and
      further agreements and/or documents and/or instruments and do such things
      as the Agent in its sole discretion may deem to be necessary to carry out
      the true intent of this Guarantee Agreement and any Mortgage and of the
      obligations secured hereby.

            Section 8.09. Counterparts. This Guarantee Agreement and any
amendment, waivers, consents or supplements hereto may be executed in two or
more counterparts, any by different parties hereto in different counterparts,
each of which when so executed shall constitute an original, but all of which,
when taken together, shall constitute but one Guarantee Agreement.

            Section 8.10. Entire Agreement. This Guarantee Agreement constitutes
the entire agreement between the parties hereto pertaining to the subject matter
hereof and supersedes all prior and contemporaneous agreements, understandings,
negotiations and discussions, whether oral or written, of the parties, and there
are no warranties, representations or other agreements between the parties in
connection with the subject matter hereof except as specifically set forth or
incorporated herein.

            Section 8.11. Headings. Section and paragraph headings and the table
of contents are not to be considered part of this Guarantee Agreement, are
included solely for convenience and are not intended to be full or accurate
descriptions of the contents thereof. Sections and paragraphs mentioned by
number only are the respective sections and paragraphs of this Guarantee
Agreement. The use of the terms "herein", "hereunder", "hereof', and like terms
shall be deemed to refer to this entire Agreement and not merely to the
particular provision in which the term is contained, unless the context clearly
indicates otherwise.

            Section 8.12. Successors and Assigns. All Persons shall be deemed to

Lending Office, of payment instructions in respect of all payments to be made to

reasonably request.

            Section 8.16. No Third Parties Benefited. This Guarantee Agreement
is made and entered into for the sole protection and legal benefit of the
Counterparties and the Agent, and their permitted successors and assigns, and no
other Person shall be a direct or indirect legal beneficiary of, or have any
direct or indirect cause of action or claim in connection with, this Guarantee
Agreement.

            Section 8.17. Equitable Relief. Each Subsidiary Guarantor recognizes
that, in the event it fails to perform, observe or discharge any of its
obligations or liabilities under this Guarantee Agreement or any of the other
Transaction Documents, any remedy at law may prove to be inadequate relief to
the Counterparties or the Agent; therefore, each Subsidiary Guarantor agrees
that the Counterparties or the Agent, if the Counterparties so request, shall be
entitled to temporary and permanent injunctive relief in any such case without
the necessity of proving actual damages

            Section 8.18. Notice of Claims; Claims Bar. EACH SUBSIDIARY
GUARANTOR HEREBY AGREES THAT IT SHALL GIVE PROMPT NOTICE OF ANY

TO THE CONTRARY CONTAINED IN THIS GUARANTEE AGREEMENT, EACH PARTY HERETO HEREBY
AGREES THAT IT SHALL NOT SEEK FROM ANY OTHER PARTY HERETO, UNDER ANY THEORY OF
LIABILITY, INCLUDING, WITHOUT LIMITATION, ANY THEORY IN TORTS, ANY SPECIAL,
INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES.

            Section 8.20. Consent to Jurisdiction. (a) Any legal suit, action or
proceeding against a Credit Party arising out of or relating to this Guarantee
Agreement or any other Transaction Document, or any transaction contemplated
hereby or thereby, may be instituted in any federal or state court of competent
jurisdiction in The City of New York, State of New York, and each Credit Party
hereby irrevocably submits to the jurisdiction of any such court in any such
suit, action or proceeding. Each Credit Party hereby waives, to the fullest
extent permitted by applicable law, any defense which it may now or hereafter
have based upon lack of personal jurisdiction or venue or forum non conveniens.
Each Credit Party hereby irrevocably appoints and designates Corporate Creations
Network, Inc., having an address at 277 Broadway, Suite 510, New York, New York
